High-capacity PF correction provides 300 kVAR total, configured as six 50 kvar steps. With a 361 A rating at 60 Hz and 480 V, the bank rapidly attenuates reactive power, lowering line losses and stabilizing voltage under peak demand. In manufacturing plants, this translates to improved motor efficiency and reduced demand charges. Rugged construction uses heavy-duty capacitor cells and protective fuses, delivering long life and safer maintenance in harsh plant environments. The unit’s dimensions (25 in length, 80 in height, 41.3 in width) and weight (820 lb) support reliable installation in standard switchgear rooms. UL 508A and UL 810 compliance simplify integration with existing panels and control systems. Designed for retrofit or new installs, it complements Eaton’s LV AutoVAR family and reduces spare-part complexity. Ongoing service and a strong warranty reduce total cost of ownership over the system lifecycle.

FAQs
The 300TPHSR431 PF capacitor bank is designed for 480V three-phase service. Plan for enclosure clearance and mechanical support to handle the 820 lb weight, and ensure available footprint approximately 25 in deep, 41.3 in wide, and 80 in tall. Connect via appropriate bus bars with protective fuses and confirm compliance with UL 508A and UL 810 standards. Engage qualified personnel for commissioning to minimize risk and ensure proper coordination with existing protection schemes.
Expect a significant reduction in reactive current and improved voltage stability across loaded feeders. The unit provides 300 kVAR total (6 Ă— 50 kvar steps) at 480 V, 60 Hz, with a 361 A rating, which helps lower energy losses, reduce demand charges, and improve motor efficiency in manufacturing lines, data centers, and process industries under typical peak-load conditions.
The product is UL Listed and CSA Certified, with UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These attest to electrical safety, control-panel compatibility, and performance reliability, simplifying regulatory compliance for industrial facilities and helping prevent acceptance delays during audits.
Maintenance focuses on regular inspection of fuses and capacitor cells, verifying tight connections, and monitoring for signs of capacitor wear or imbalance. The unit’s heavy-duty cells are designed for long life, but periodic checks reduce fault risk. Eaton provides standard support and warranty coverage to address component wear, with a one-year warranty from installation or 18 months from shipment per policy 25-000.
Eaton provides a one-year warranty from the installation date or 18 months from shipment, whichever occurs first (policy 25-000). Post-installation support includes technical assistance, replacement of defective components, and guidance on PF correction optimization. This helps ensure sustained performance, reduces downtime, and supports a favorable total cost of ownership for industrial capital equipment.
